| x-3 | &lt; x-3<br><br> can someone give a step by step process on how to do this?
statuscvo [17]

Answer:

There are no solutions to the inequality.

Step-by-step explanation:

|x - 3| < x – 3

1. Separate the inequality into two separate ones.

(1) x – 3 < x – 3

(2) x – 3 < -(x – 3)  

2. Solve each equation separately

(a) Equation (1)

\begin{array}{rcl}x - 3 & < & x - 3\\x & < & x\\\end{array}\\\text{This is impossible. No solutions exist.}

(b) Equation (2)

\begin{array}{rcl}x - 3 & < & -(x - 3)\\x - 3 & < & -x + 3\\x &

For example, if x = 0, we get  

|0 - 3| < 0 - 3 or

3 < -3

A random variable is uniformly distributed over the interval [-4, 6]. find the mean, variance, and standard deviation of .
Lyrx [107]

The mean, variance, and standard deviation are 1, 8,33 and 2.89

<h3>How to find the mean, variance, and standard deviation?</h3>

The distribution is given as:

[a, b] = [-4, 6]

The mean is calculated as;

Mean = (a + b)/2

So, we have

Mean = (-4 + 6)/2

Evaluate

Mean = 1

The variance is calculated as;

Var = (b - a)^2/12

So, we have

Var = (6 + 4)^2/12

Evaluate

Var  = 8.33

The standard deviation is calculated as;

SD= sqrt(Var)

So, we have

SD = sqrt(8.33)

Evaluate

SD = 2.89

Hence, the mean, variance, and standard deviation are 1, 8,33 and 2.89
